5.1. GENERAL DESCRIPTION & INTENDED USE
The
HI97723
is an auto-diagnostic portable photometer that benefits from Hanna’s
years of experience as a manufacturer of analytical instruments. It has an advanced
optical system that uses a Light Emitting Diode (LED) and a narrow band interference
filter that allows for accurate and repeatable readings.
The optical system is sealed from outside dust, dirt and water. The meter uses an
exclusive positive-locking system to ensure that the cuvettes are placed into the holder
in the same position every time.
With the CAL Check™ functionality, users are able to validate the performance of the
instrument at any time and apply a user calibration (if necessary). Hanna Instruments
CAL Check cuvettes are made with NIST traceable standards.
The built-in tutorial mode guides users step-by-step through the measurement
process. It includes all steps required for sample preparation, the required reagents
and quantities.
The
HI97723
meter measures the chromium content in water samples in the 0 to
1000 µg/L (ppb). The method is an adaptation of the ASTM Manual of Water and
Environmental Technology, D1687-92, Diphenylcarbohydrazide Method.
The
HI97723
photometer is a compact and versatile meter suitable for field or bench
measurements, featuring a:
• Sophisticated optical system
• Meter validation using certified CAL Check cuvettes
• Tutorial mode guides the user step-by-step
• Auto logging
• Waterproof IP67, floating case
• GLP features
